Bottle closure and method of using the same

摘要

A bottle closure (100) for a bottle (200) comprises a first closure (500) securable over an opening of the bottle (200). The first closure (500) having a central generally circular projection (540), and a liquid flow aperture (512) located adjacent to the projection. A second closure (600) is located over the first closure (500), the second closure (600) having a generally circular aperture (632) adapted to receive the circular projection (540), the second closure (600) being movable between a first position and a second position. In the first position the circular projection (540) generally occludes flow through the circular aperture (632), and in the second position the circular projection (540) is adjacent to the circular aperture (632), providing a fluid flow path from the bottle, through the liquid flow aperture (512) and the circular aperture (632). The first closure (500) includes a first engagement formation (504) and the second closure (600) includes a corresponding second engagement formation (602). The first and second engagement formations (504, 602) being adapted to move the second closure (600) both longitudinally and pivotally about a longitudinal axis (XX) as the second closure (600) moves between the first position and the second position.

1. A bottle closure for a bottle, the bottle closure comprising:
a first closure securable over an opening of the bottle, the first closure having a central generally circular projection, and a liquid flow aperture located adjacent to the projection; a second closure located over the first closure, the second closure having a generally circular aperture adapted to receive the circular projection, the second closure being movable between a first position and a second position, wherein in the first position the circular projection generally occludes flow through the circular aperture, and in the second position the circular projection is adjacent to the circular aperture, providing a fluid flow path from the bottle, through the liquid flow aperture and the circular aperture; further wherein the first closure includes a first engagement formation and the second closure includes a corresponding second engagement formation, the first and second engagement formations being adapted to move the second closure both longitudinally and pivotally about a longitudinal axis as the second closure moves between the first position and the second position.
